What is SIPROTEC 4?

SIPROTEC 4

is the family of numerical

Protection, Control and Substation Automation devices

by

SIEMENS


The protection functions are not new!

They were therefor largely taken over from existing devices.

What is SIPROTEC 4?


The optional integrated local and remote control

SIPROTEC 4 What makes these devices so attractive ?

SIPROTEC 4Distance protection 7SA6 - Highlights

7SA6 = Distance protection range for MV, HV and EHV

7SA6 includes all the functions of 7SA511/510 and 7SA513 Distance protection always with 6 measuring systems, fault detection selectable as

either I>, Z<, U/I and U/I/ Can be applied in systems with compensated, isolated or solid earthing Scope of functions and measurements increased in comparison with 7SA51

Housing and input/output version for each application

All protection functions are available in all housing versions

SIPROTEC 4 = Programmable logic, control, interlocking local control is optional

SIPROTEC 4 = Communication interfaces Various tele-control protocols and physical connections options are available Via serial interface, tele-prot. can be implemented with standard comms. networks

(G703, V11/X21) or async. direct connection (not available at product launch)

7SA6Some enhancements

Distance protection always with 6 measuring systems, fault detection I>, Z<, U/I or U/I/

very fast tripping timesvery good selectivity and system stability

Automatic reclosure with additional functions DLC (closing only when there is no voltage on the line) ADT (closing only when reclosure at remote end is successful) RDT (shortened dead time following TRIP by overreaching zone)Saves plant and avoids unnecessary dead times

Operational measured values comprehensive selection of measurands, tolerance <1%Measurement transducers are no longer required


Coupling to conventional Tele-control 20mA interface for analogue measured value and fault location output BCD-Measured value and fault location output 7SA6 is perfectly suited for integration in existing substations

Breaker failure protection, 2-stage

Back-up earth fault protection for earthed systems 4-stage, sensitivity 0,5% IN high sensitivity and selectivity, also in the event of high resistance faults

Voltage protection U> and U< ULE, ULL, U0, U1, U2

Distance Protection SIPROTEC 4 Auto-Reclosure (2)

Remote close command from ARC master to opposite line end

Separate dead times for all ARC cycles

Three pole coupling of trip command for implausibility

Integrated dead time monitoring

Integrated circuit breaker monitoring and plausibility check

Integrated evolving fault recognition and treatment

Automatic blocking of the ARC following manual close or open CB condition

Initiation of ARC by internal or external functions

Support of 1 ½ and double circuit breaker applications


Slave provides close command when: the remote close command is received from the master (remote station) or healthy voltage (3-phasig) is measured for

a settable time CB-ready state prevails (selectable) Sync-check release was given (selectable)

No repeated closure onto faults (improved system stability)

Reduces stress of CB poles (longer maintenance cycles)
